The jet engines were brought up to speed and a frozen ( animal rights against using live) chicken was "shot" into the engine and the effects then monitored. This aids in the design of fan blades that will spin foreign objects out into the area of high bypass and not into the compressor section of the engine. FAA also has blade containment specs that must be tested for and met. After the ingestion takes place IF fan/compressor blades are released, the parts must be contained within the casing/nacelle.
